(57) [Problem] To provide a catalyst which efficiently decomposes global warming gas and has a long service life, and a decomposition method using the same. In a reaction for decomposing a global warming gas in a gas phase in the presence of water vapor or water vapor and molecular oxygen, sulfates are converted to aluminum, boron, alkaline earth metal, titanium, zirconium, lanthanum, cerium, yttrium. A method for decomposing a global warming gas using a catalyst comprising an oxide of sulfur and at least one element selected from the group consisting of rare earth metals, vanadium, niobium, chromium, manganese, iron, cobalt and nickel. |
